+CORRELATOR_NOTES

Scan at 230-0607 produced a zero code on S/X band.
The source being observed was 1038+52B.
Scan at 230-0631 and 230-0658 produced a zero code on S/X band.
The source being observed was 2021+614 for these scans.
Scan at 230-0633 produced a zero code on X band.
The source being observed was 1823+568.
There was good integration time but low SNR for them.


+STATION_NOTES

KOKEE   (K-Kk): OK.
                Transfer rate: 200 Mbit/s

SVETLOE (S-Sv): Manual pcal applied at SVETLOE.
                Svetloe maintained very low amplitudes across all
	        channels on X-band throughout experiment.
                Transfer rate: 250 Mbit/s

KOKEE data were transferred to Tsukuba by
